IDENTIFYING FACTORS THAT WORSEN IN-HOSPITAL OUTCOMES IN PATIENTS WITH VENTRICULAR TACHYCARDIA (VT) AND INFLAMMATORY BOWEL DISEASE (IBD)

Abstract

Abstract BACKGROUND IBD is a proinflammatory state that can have numerous complications involving all systems of the body. There is a known association with cardiovascular disease. However, there are limited studies that have examined the impact of cardiac arrhythmias such as VT on patients with IBD (Crohn’s Disease and Ulcerative Colitis). The aim of this study was to evaluate the economic burden and various hospital outcomes associated with patients with IBD with and without VT. METHODS Patients aged 18 years with IBD and VT versus IBD alone were identified from the US Nationwide Inpatient Sample (NIS), from the years 2010-2019. ICD 9 and 10 codes were utilized and multivariate regression analysis utilizing propensity matching (Kernel method) was used to estimate the odds ratios of in-hospital mortality, the average length of hospital stay (LOS), and hospital charges (TOTHC), after adjusting for age, gender, race, primary insurance payer status, hospital type and size (number of beds), hospital region, hospital teaching status, and other demographic characteristics. Weighted analysis utilizing Stata 17 MP was performed. RESULTS For patients with Crohn’s disease and depression, mean age at readmission was 51.6 years and there was a high readmission rate and mortality at 30 days (readmission rate 5.2%, p<0.01 and mortality rate 2.8%, p<0.01) which increased significantly at 90 days (readmission rate 8.4%, p<0.01). Hospital LOS and TOCHG remained relatively the same compared to the index admission for both 30 day and 90 day readmissions (Table 1). A very similar trend was seen for UC and depression as well: mean age at readmission was 51.4 years and there was a high readmission rate and mortality at 30 days (readmission rate 5.0%, p<0.01 and mortality rate 2.6%, p<0.01) which increased significantly at 90 days (readmission rate 8.4%, p<0.01 and mortality rate 2.9%, p<0.01). The top 10 causes of readmission at 30 days and 90 days for both UC and Crohn’s are summarized in Table 1. CONCLUSION Our study revealed that patients with IBD and VT had increased mortality, LOS, and TOTHC were increased compared to patients with IBD only. Further studies are required to further evaluate this patient population.
